METAL AXIAL VENTILATORS Description and specifications: MAV ventilators are high efficiency duct ventilators, designed to increase airflow performances and lower noise emission. The ventilators have diameters ranging from 300 mm to 1250 mm. The ventilators normal working temperatures range from -40° C to +120° C, and can reach up to 200/300° C with customized solutions. Applications: Residential and industrial HVAC/R, radiators, heat-exchangers, ventilation for livestock, dryers and kilns. Impeller: MAV ventilators can be assembled employing a variety of HW Ventilation fans. Fixed pitch axial flow fans – 6/8/10/14 blade configurations • TS (subtypes G, D) – airfoil profile axial impellers, diameters from 230 mm to 906 mm • Q – sickle profile axial impellers, diameters from 230 mm to 750 mm Variable pitch axial flow fans – 5/9/12/16 blade configurations • TM (subtypes N, V) – airfoil profile axial impellers, diameters from 300 mm to 1270 mm • R – reversible axial impellers, diameters from 550 mm to 966 mm • SR – sickle profile axial impellers, diameters from 550 mm to 1100 mm • C – sickle profile axial impellers, diameters from 450 mm to 1282 mm All HW Ventilation impellers have been tested against ErP 2015 directive for energy efficiency of axial fans in our AMCA 210-07 wind tunnel.
